14 RCC-1055 CD Multi-Disc Changer
Troubleshooting
Most difficulties in audio systems are the result
of incorrect connections, or improper control
settings. If you encounter problems, isolate the
area of the difficulty, check the control settings,
determine the cause of the fault and make the
necessary changes. If you experience problems
with the RCC-1055, refer to the suggestions
for the following conditions:
Display Is Not Lit
The Disc, Track and Time indicators in the dis-
play should be lit whenever the power switch
of the RCC-1055 is pushed in. If the display
does not light, test the power outlet with another
electrical device, such as a lamp. Be sure the
power outlet being used is not controlled by
a switch that has been turned off.
Fuse Replacement
If another electrical device works when plugged
into the power outlet, but the RCC-1055 display
will not light when the power switch is pushed
in, it indicates that the internal power fuse may
have blown. If you believe this has happened,
contact your authorized Rotel dealer to get the
fuse replaced.
Disc Does Not Play
If a disc does not begin playing when the Play
button is pressed, open the disc tray and be
sure the disc is loaded with the label side up.
If a disc is properly loaded, inspect the playing
side of the disc for contamination or damage.
If the disc is dirty, clean it as described in the
Handling Compact Discs section. If a disc is
damaged it should be replaced.
No Sound
Check the input selector on the amplifier to be
sure it is properly set. Check the tape monitor
switches to be sure they are properly set. Check
other signal sources to be sure the amplifier
is operating properly. Finally check the audio
cables between the RCC-1055 and the amplifier
to be sure they are properly connected.
Sound Skips
If the sound from the RCC-1055 skips or jumps
around, the disc may be defective or dirty. If
the disc is clean, try another disc. If a problem
persists it could be caused by vibrations reach-
ing the RCC-1055. Sound vibrations, especially
from a subwoofer, can interfere with the laser
reading a disc surface. Move the RCC-1055 to
a more stable surface, or to a location farther
away from the speakers.
Hum
Hum is caused by electrical interference from
other devices. It is most often picked up by the
audio signal cables. Use high-quality cables.
Low quality cables often have inadequate
shielding. Check to be sure the cables are
solidly connected to both the RCC-1055 and
the amplifier. Try moving the cables to a position
farther away from other electrical components,
especially power amplifiers which have large
power transformers. Other devices that com-
monly cause interference are fluorescent lights
and light dimmer controls.
